MACHINE FOR INSERTING SLIPS IJ NTO PACKAGES I Application m August 18, 1830. Serial No. 475,953.

This invention relatesto mechanism for inserting slips into packages which have previously been wrapped and cartoned, and an object is to provide a simple and efficient '5 machine for automatically inserting a predetermined number of slips into the package after the latter is completely closed. I

Further objects of the invention consist in the construction and arrangement of elements, and their operation, and res de mthe new and improved features hereinafter appearing. I I

By way of illustration, but not oflinntation, the invention is shown on the accompanying drawings, in which: II

In thepackaging of some materials, it is desirable to insert a slip. within the package. For example, in the packaging of oleomargerine, which must be packaged in its natural color, it'is desirable to include within the 'package'a slip containing coloring material so that the purchaser may, at his option, mix 4. the coloring material into the oleomargarine. o0 Oftentimes the producer desires to insert within the package a small slip containing advertising matter. In accordance with this invention, a simple and efiicient machinehas been produced which automatically inserts a predetermined number ofslips within the package after the latter is completelyclosed. I Heretofore devices have been roduced for inserting slips into packages during the packagingof the articles. Many of these have been found unsatisfactory due to the fact that the slip is not positively included in the package, and it not infrequently happens that after the package is completely formed, for one reason or another, the slip is not contained therein.

Referring to the drawings wherein the invention is illustrated, a uide 1 is provided, are step-by-step mechanism. The cartons are of the usual I type, being of card board with paneled sides and completelyenclosing the article or articles disposed therein. .The paddles 2 (as shown three are employed for completing the advancing movement of the packages from the carton wrapping mechanism) move the cartons to a supplemental guide 3, each carmechanism hereinafter described. As shown, a platform 4 rising from the guide 1, being supported by legs 5, supports-v a partial vacuum generating device generally indicated by the reference character 6. Leading from this apparatus is a tube 7, which conne'ctsat its lower end with a guide tube 8, in which .a suction tube ,9 is reciprocable, the upper end of this tube being closed except serving yieldingly to urge the tube 9 downa pocket to contain the coloring material in powdery form. The lowermost slip rests adacent its outer edges on spaced rollers 15 (Fig. 2). The rollers 15 alone hold the stack of slips S and are carried by plateslfi secured to, the machine frame 17."

Carried by the suction head 12 is a disc 18 having a pair of-elongate slots 19. The arrangementis such that when the head 12 descends suction is momentarily imparted to the lowermost slip, S, the tube 7 being in communic'ation through the openings 13 with the tube 9, thereby causing the adjacentslip to adhere to the head 12, and as the edges of the slip ass over the rollers 15 the slip tends to buc e or bow downwardly, thereby prevent ing additional slips from assing over the rollers. It has been found t at the rollers 15 are advantageous since they militate a ainst becoming coated with adhesive materi from the sli s. It will be understoodthat the slips are 0 n coated with paraflin, and should they pass continuously over the same surface, such surface will in time become coated with the parafiin from the slips, which interferes with the proper functionin of the apparatus. Carried by the underside of the head 12 is a roller 20 which is held yieldingly in en.- gagement with a cam 21 by the s ring 11. The cam 21 is so shaped that vertica recl rocatory motion is imparted to the head 1 recurrently so that individuallyslips are removed from the receiver 14. Soon after the head 12 starts i$ descending movement the artial vacuumis released and the sli S is can ht by hooks 22 carried by spaced discs 23. I onnected to drive the discs 23 is a gear 24, which is driven by a pinion 25. The pinion 25 is mounted on the shaft 26 to which power is applied through a sprocket and chain connection 27. As shown, each disc 23 is formed with two hook members 22, which are diametrically o posed.

.When the'head 12 isin Its lowermost position a pair of hooks 22 engage the slips S and move them in a clockwise direction (Fi '8) toward a depending curved guide 2 During the movement of the slips to the guide 27, a pair of weighted transversely spaced arms 22' engage opposite side ortions of each slip and tend-t0 square an retard the same. The arms 22' are ivoted and depend on the outer sides of the iscs 23.

" advanced to the supp on a common shaft 29, towhich rocking move ment is recurrently imparted byan. arm 30 carryin a roller 31 engaging a cam 32 mounted on the shaft 26. A; coil spring 33 holds the roller 31 in'engagement with the peri hery of the cam 32.

T e fingers 28. force "the slip S through a guide which is positioned directly above a carton O. v.Thefguide consists of a pair of plates 34 which are mounted on transverse rods 35 and 36', which in turn-are supported 2y horizontal arms 37 and 38 respectively. he latter are suitably connected to the ma chine frame 17. I Disposed on the inner sides.

of the plates'34'are vertically inclined guide rails 39' -which receive the side portions of the slip and conduct the same to the carton C disposed therebeneath. v

As above explained the filled carton O is lemental guide 3. On

this guideis mounted a device for outwardly bowing one panel of the "carton to providea pocket into which a'slipj Sisjnserted. A's clearly shown in:Fig.,j4,;brackets;39 are secured to opposite sides of-th1efguide 3' and pressure plate's'40 eng e the-'inner-sides of the brackets 39. 1 Forfyieldin'gly urgingthe plates inwardly' j toward *sach "other 5 coil springs 41 bear againstthebrackets'39 at one end and against nuts 42 mounted on rods 43 at the oppositejend .The'ro'ds 43 are carried by the plates) justa'ble'stop screws 44 are provid 01, ,en'd'sbfthe lates 40 for hmitin theirouteijposition. s shown in'Fig.4', t e lates 40. cooperate to outwardly bow a pane P of the carton O and provide a pocket L into. whichthe slip S is inserted. As shown in Fig. 6,"the" sli guide is positioned directly above the pd'c 'et L so that the pushing fingers 28 operateto positively force the slip S into th'eca'rton; As indicated by the dotted lines on Fig. 3, thefingers 28 move substantially into en ement with the car,- ton, thereby to'iiisiirg tiat the slip is forced directly into the carton. As the next succeeding carton C advances panel which has been bowed, an returns the sameto normal position and moves this carton ahead.

In the alternate form shown in Figs. 7 to 10, inclusive, a depending wedge shaped finger 45, which is pointed at its lower end, is pivoted to an arm 46, which is fixed to a shaft 47. Carried by the shaft 47 is an arm 48 carrying a roller 49, which is held in engagement with a cam 50 on the shaft 46 by a coil spring 51. Adjacent the guide it engages the rear of the slipxguide finger 45 is a locatin finger 52. The finger 52 1s also pivoted to t e arm 46 and is curved rearwardly in a direction opposite to the direction'of movement of the cartons C. The lower end ofthe locatin finger 52 extends beyond the pointed end 0 the guide finger 45 and is disposed sli rearwardly thereof. A set screw 53 carried y the locatin finger 52 engages the guide finger 45 and ena les the htly two fingers to be adjusted initially relative to each other so as to bring their lower ends closer together or farther apart, as thereguirements demand. Carried by the guide 11 er 45 is a bracket 54 which carries a spring 55 earin-g against the locating finger, thereby yielding'ly to hold'ithe fingers in their proper position relativeto each other.. In

I order to return the .fin ers 45. and '52 to their it is not necessary that the ends of the carton j be squeezed to form the pocket L, since the locating finger 52 engages then per reared of the carton Gdisposed there eneath," T e' finger 52'rides over this edge and properly positions-the guide fin er 45 relative to the pocket L and permits t e guide finger to e'x-r tend into-the pocket." When the guide finger .45 is" in this position the pushing fingers 28 aboverde scribed descend andpositivel force the slip S inside of the carton In this form fingers45 and 52 cooperate to open the car- ,ton panel sufiicient to receive the slip S.

It is to be understood that the above de-. scription is given by way of illustration and not of limitatiomand numerous changes in details of construction, arrangement of parts,

" and of operation, may be efiected without departing from the spirit of the invention,-es-' pecially as defined in the What is claimed:
